OCS extrusion direction for LWPOLYLINE about dxf-parser

[bzuillsmith]

Oh, you're right, this function will run to the end of the entity. I never needed to implement anything 3D so I didn't test or think about that.

Yeah, those could really be moved out to the entity. We just need to identify all the codes that are possible on the vertices section (if there are more than what's there already). Then the default case in this switch you posted could stop parsing the vertices and return without advancing the scanner.

Do you want to give that a try and submit a PR?

As for the OCS to world stuff, I wrote three-dxf which uses three.js under the hood. Not sure, but maybe Three.js will take care of that for you (assuming you are able to use it in your project).

Maybe just return on default case?

I also use three js. Three would handle it if you put the lines in parent object then rotate the parent, but I need a 2d drawing and don't want to have to rely on three js libs for canvas drawing. I found some c code that I could port over... I'll look through the 3dxf code. I have some tricks iplemented for large dxf files, and would love to pick up any optimizations you have.

I'll do a PR tomorrow. Thanks
